# Qwen2.5-Coder-14B-n8n-Workflow-Generator
|
|
|
|
|
|
|
|
Fine-tuned Qwen2.5-Coder-14B-Instruct model specialized for generating n8n workflow JSONs from natural language descriptions.
|
|
|
|
## Model Description
|
|
|
|
This model is a QLoRA fine-tuned version of [Qwen/Qwen2.5-Coder-14B-Instruct](https://huggingface.co/Qwen/Qwen2.5-Coder-14B-Instruct) on the [n8nbuilder-n8n-workflows-dataset](https://huggingface.co/datasets/mbakgun/n8nbuilder-n8n-workflows-dataset), containing +2.5K n8n workflow templates.
|
|
|
|
**Training Details:**
|
|
|
|
- **Base Model**: Qwen/Qwen2.5-Coder-14B-Instruct
|
|
- **Method**: QLoRA (4-bit quantization)
|
|
- **LoRA Rank**: 32
|
|
- **LoRA Alpha**: 64
|
|
- **Training Steps**: 432 (3 epochs)
|
|
- **Sequence Length**: 8192 tokens
|
|
- **Learning Rate**: 2e-4
|
|
|
|
## Usage
|
|
|
|
### Transformers
|
|
|
|
```python
|
|
from transformers import AutoModelForCausalLM, AutoTokenizer
|
|
import torch
|
|
|
|
model_name = "mbakgun/Qwen2.5-Coder-14B-n8n-Workflow-Generator"
|
|
tokenizer = AutoTokenizer.from_pretrained(model_name)
|
|
model = AutoModelForCausalLM.from_pretrained(
|
|
model_name,
|
|
torch_dtype=torch.bfloat16,
|
|
device_map="auto"
|
|
)
|
|
|
|
system_prompt = "You are an expert n8n workflow generation assistant. Your goal is to create valid, efficient, and functional n8n workflow configurations."
|
|
|
|
user_input = "Create a workflow that monitors a RSS feed and sends new items to Discord."
|
|
|
|
prompt = f"{system_prompt}\n\n{user_input}"
|
|
|
|
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
|
|
outputs = model.generate(
|
|
**inputs,
|
|
max_new_tokens=4096,
|
|
temperature=0.7,
|
|
do_sample=True
|
|
)
|
|
|
|
workflow_json = tokenizer.decode(outputs[0], skip_special_tokens=True)
|
|
print(workflow_json)
|
|
```
|
|
|
|
### MLX (Apple Silicon)
|
|
|
|
```bash
|
|
# Download MLX Q4 model
|
|
mlx_lm.generate \
|
|
--model mbakgun/Qwen2.5-Coder-14B-n8n-Workflow-Generator/mlx-q4 \
|
|
--prompt "You are an expert n8n workflow generation assistant...\n\nCreate a workflow that sends Slack notifications when GitHub issues are created." \
|
|
--max-tokens 4096
|
|
```
|
|
|
|
## Training Data
|
|
|
|
This model was fine-tuned on the [n8nbuilder-n8n-workflows-dataset](https://huggingface.co/datasets/mbakgun/n8nbuilder-n8n-workflows-dataset), which contains:
|
|
|
|
- **+2,304 workflow templates** (after filtering sequences >8192 tokens)
|
|
- Format: Alpaca (instruction/input/output)
|
|
- Source: n8n.io public template gallery
|
|
- [n8nbuilder.dev - Create n8n Workflows in Seconds with AI](https://n8nbuilder.dev)
|
|
|
|
## Performance
|
|
|
|
- **Training Speed**: ~33.85s/step on H100 PCIe
|
|
- **VRAM Usage**: ~30GB (4-bit QLoRA)
|
|
- **Inference**: ~25-40 tok/s on Mac Mini M4 64GB (MLX)
|
|
|
|
## Limitations
|
|
|
|
- Generated workflows may require manual validation
|
|
- Long workflows (>8192 tokens) may be truncated
|
|
- Model trained on public templates only
|
